슬래브궤도의 구조 안전성 평가

초록

In recent years, the destructive force acting on the ballasted track is on the increase with the speed-up of trains and the number of trains, requiring more labor and expenditure to maintain the track in good condition. Slab track has been developed to decrease the track maintenance work on earthworks. One type of slab track Rheda has prefabricated track grid, consisting of rails, prestressed concrete sleepers and reinforcement rods are aligned into position, and then concrete is then placed to integrate the sleepers into a reinforced concrete track slab. In this paper, a new analysis model for the system analysis of the slab track is presented. Then the analysis results are compared with requirements for slab track.
